Can someone who's been there tell me how the "Trusted by developers, startups, and Fortune 500s" works? How does Retool (or any company) get another company's logo here?
Getting permission is definitely not a sure thing and might require some luck or savvy, or having a champion with clout (director, VP, etc…)
For a lot of companies, logos on homepages is more of an “ask for forgiveness later” type of thing. Not uncommon to do it without permission.
It’s also very common for TOS to include the rights to use your company logo for marketing purposes by default.
